Cathi:
Before we go more further, the value was already sent to the regex.replace command before I add to the control? Maybe the Regex.replace command have problem and is sending a null value. Remember that I am sending a space(1) when I initialize the row. Also I dont know if I told you but my regex.replace command reject the (string), I have to formated with only three parameter instead of four like your example. Let me know if this is the problem.
